3 Maintenance and service

When designing this device, Hirschmann was largely able to forego using
parts that are subject to waer and tear. The parts subject to wear are
designed to last longer than the lifetime of the product when it is operated
properly. Operate this device according to the specifications (see
“Technical data” ).

Relays are subject to natural wear. This wear depends on the frequency
of the switching operations. Check the resistance of the closed relay
contacts and the switching function depending on the frequency of the
switching operations.
